Sadly though, the films have been stored in the usual compressed way. For laminar flow visualization, this works fine. Unfortunately, the film on turbulence suffers from nasty compression artifacts that obscure the time-dependent, chaotic structure this video was designed to illustrate. It'd be interesting to know if there are domain-specific codecs that would adequately capture chaotic motion here, or if all compression approaches would suffer a similar fate. In theory, you probably could capture the isotropic small scale structure and then overlay that atop a normal video codec to get acceptable results.
